Can anyone find this?
Their latest bulletin[1] doesn't seem to say this as far as I can see.
There is "East Africa: Prices of coarse grains followed mixed trends in April; exceptionally high levels persist in the Sudan and South Sudan" but that seems to be offset by "Domestic prices of rice generally stable in April with exception of some main exporters where they decreased; those of wheat followed mixed trends"
Their price trend release[2] is also mixed news.
